Do I need optical attenuators for short-distance connections with the XS+31LC20D?

For bench testing or short fiber runs under 2 km, you must check the optical receiver power via Digital Diagnostics Monitoring (DDM) to prevent receiver saturation or damage. If your link is short and signal levels exceed the maximum optical input rating, an in-line optical attenuator is required.

What warranty and repair coverage is provided when buying from Apsardze24.lv?

All units purchased from Apsardze24.lv include a 2-Year Warranty for both private and business clients. Local warranty service is handled directly from Riga, ensuring fast diagnostics and rapid shipping across Latvia, Estonia, and Lithuania.

What type of optical fiber cable and connector does the XS+31LC20D transceiver require?

It requires a standard 9/125 µm Single-Mode Fiber (SMF) terminated with a dual LC-UPC (blue) connector. It is not suitable for multi-mode fiber (MMF) or angled polished LC-APC (green) connectors.

Is the MikroTik XS+31LC20D compatible with third-party switches like Cisco or ubiquiti?

While MikroTik transceivers follow standard MSA compliance and work seamlessly across MikroTik hardware, third-party vendor locks may affect detection on proprietary switches. If you have specific brand compatibility questions, contact technical support at [email protected].

Does the XS+31LC20D support real-time optical diagnostics in RouterOS?

Yes, the module features integrated DDM (Digital Diagnostics Monitoring), enabling you to monitor optical TX/RX power, temperature, supply voltage, and bias current in real time directly from RouterOS or via SNMP.

Can the MikroTik XS+31LC20D work in standard 1G SFP or 10G SFP+ ports?

Yes, the XS+31LC20D is multi-rate and backward compatible with standard 1.25G SFP, 10G SFP+, and 25G SFP28 interfaces. Note that in some RouterOS configurations, you must disable auto-negotiation and manually set the port speed (1G or 10G) to link properly.
